To all .whom it may concern Be it known that I, HENRYB. SAUERMAN,

a citizen of thel nited States, residing at Chicago, in the county of Cook and State if Illinois, have invented new and'usetul lm- -prov'ements in Scraper Apparatus, of which the followingy is a specification.r

. My invention relates to the type of scraper or dredge apparatus involving, generally stated, an inclined main cable, a carriage movably supported on said cable, a scraperbucket supported from said 'carriage in a y manner to permit it to be moved lthereonl ranged.

from. lling' position to dumping position and vice verse., and means for hauling the carriage and bucket up said main cable to the dumping point. I

My object is to provide 'for the automatic dumping ot' the bucket at a predetermined point, by means which shall be simple and economical of manuiactureand which will not' be liable to become Referring to the accompanying drawings, Figure l is a view in eleva-tion of an apparatus constructed in accordance with my in- Vention, the apparatus being shown in' the 'position is assumes when dredging, the conn struction shown constituting what now re gard as the preferred embodiment of my 1nventlon. Fig. 2 1s a similar view of a part of the main and hauling cables and the carriage and bucket of Fig. l, this view showing the main cable tautand the bucket in the position it. assumes While being moved up on the main. cable through the `rnediiun of the hauling cable, tloe carriage and bucket bein g shown in: a position closely adjacent to the point of dump1ng.

Fig. 3 isa view like Fig. 2 showing the vbucket in 'the act of dumping. Fig. i is a plan view of the main cable and carriage thereon. Fig. 5 is a rear end view of the `carriage and bucket carried thereby.

ig. 6 is 'an enlarged section taken at the line 6 on Fig. 2and viewed in the direction .ot the arrow. Fig. 7 is a planview of the impaired or de- 4tion illustrated in Fig. 10; and Figs. 12and l rig. 1o is a, View like rig. e of aucuneid-i?? in which my invention may be embodied(r Fig. 11 is a view like Fig. 3 o' the construe-- '13, views like Figs. 2 and 3, respectively, et" .f is! still another embodiment o my invention.

,y The inclined main cable which would be" supported to extend across the ground. to `bef excavated or dredged, is represented -at 15 and 1s anchored at its lower end, as indicated et. 16 and -at'its opposteupper endv connectev with a tautlng mechanism of any suitable and well-lrnown construction secured to the u )per end cfa mast 17, and as shown, formed or a systemof pulleys 18 connected with acable 19 Whichpasses overa suitably oper-iff ated drum 19, whereby. the cable 15' maybe slackened or made taut at will.

Mounted on the cable 15 to travel thereon is a carriage which, inthe construction villustrated in Figs. l to 9 inclusive, is represent ed at 20, 'lhecarriage 20 is formed of two plates 21 spaced apart and connected tov gather by cross-rods 22, the upper, ones of which form journals for groovedwheels 23 located between these plates, and at which 'te'y soV the carriage is supported on the cablel tof.

permit it'to travel thereon'. l

The scraper lbucket which is represented at 24 is provided with an open end equipped with a cutting edge 25 extending in' advance thereof as is common in constructions ofv buckets of vthis type. The bucket 24 is sup ported from the .carriage 20 through. the medium of iexible connections 26 and 27. These connections may be of any suitable construction, but they are preferably provided in the form of chains, the chain 26 being connected at oneend with the lowerrear one ci' the rods 22 and between the plates 2l, and at its opposite end with the lowerv rear end of the bucket 24 as represented at 28; and the-chains 27 being connected with i I the upper rear' end of the bucket as 'represented at 29. Thechain 27 is formed of two sections, i shown in Fig. 5, the' upper ends of these -iiliain sections being connectedv beyond the plates 21 with the rear biur 5 .z

cated end 30 of e. latch-device 31 pivoted on the upner forward one of the rods 22 and extending at its shouldered section 32 med'ially of and in advance of the front end of the carriage' 20, the latch 3l being providedor.

coeeration with e block 83 having' a cane surface 34 and slidably mounted on the main A 'cable l5 .and connected means of e cham' 35 with a clamp' 36 adjustably secured. to the cable l for a purpose hereinafter' eXH plained.

l flic carriage and. bucket are adapted to be operated through the medium of a hauling cable 37 passing over a pulley on the naast: 17 and connected with a drum 39 operatedlin any suitable and well-known manner, and at its opposite end connected with the forward ends of tw!) chains 40 and 4l, the chain 40 passing over a pulley 42 rotatably mounted on. the lower forward one of the rods 22 on the carriage and connected with a cross-bar 43 at the upper front end' of the bucket, as represented. at 44; and the chain 4l connected with the sides of the bucket, as represented at 45.'

ln the operation of the apparatus, assuming it to be in scraping position, Fig. l, wherein the cable l5 is slack and the bucket 25 lies on the material to be operated on, the bucket is dragged along the material by pulling on the hauling cable 37 which causes the bucket to fill. As soon as the bucket has filled, the operator, by operating the drum 2O draws the cable l5 taut,and by continuing to pull on the hauling line 37 drags the bucket 24 and carriage 2O up the cable l5 as represented in Fig. 2, the bucket 24 duringthis operation being held in po sition for retaining its load by reason of its connections with the carriage and with the hauling cable 37, as described. The operator continues to pull'on the cable 37 until the shouldered portion 82 of the latch.` 3l passes over the blockl 33, which permits the .latch to interlock with said block, thus pre 'venting the carriage from running down on the cable l5, and permitting the-bucket 24 to swing downwardly at its flexible connection 26 with the carriage, to dumping position. The chains 26 and 27 are of suoli lengths that the chain 27 is pulled taut when the bue et swings to discharge position and thus actuates the latch-device 3l in a direc tion to raise its shouldered portion out of engagement witlc vthe block 33, whereupon the carriage `'and bucket, upon paying out the cable 37" vrun down the cable l5 to reposition the bucket for lilling.

The construction illustrated in Figs. and ll is thesame that i ust described, eX- cepting. that instead. of running the chain 40 over a pulley on the carriage 20, it is connected directly with the lower forward. one of the rods of the carriage, as represented, this rod in the' present case having no pulley. c

ln the constructionillustrated in Figs. and., lil the icarriage, which is of the saine general construction the carriage 20, represented at 46, this carriage being mounted at wheels 47 on the cable l5. The latch device in this construction for .releasably holding the carrige 46 in position while License.

the bucket is beingA dumped, is formed of a pair of bars 4SA arranged at opposite sides of the carriage and terminating at 'their forward ends in a single'latch 49 having a shouldered portion 50 and arranged to cooperate with the block 33. The rear ends of the bars 48 are connected together by a cross-rod 5l which extends through opposed slots 52 in the side plates of the carriage, and on which rod pulleys 53 are journaled, one at each side of and beyond the side plates of the carriage, the bars 48 extending at their forward ends in guides 54 at opposite sides of the carriage andconnectod together. at their rear ends by a yoke 55.

-'ll`he bucket, which is. the same as the bucket 24, is represented at 56 and is supported from the carriage 46 by flexible connections 57 and 58'. these connections preferably being chains. The connection 57 is preferably formed of two chains connected at their lower ends to the rear lower end of the bucket 56 toward opposite sides thereof, as represented of one of the chains at 59, and at their upper ends extend over the pulleys and connect with the carriage at opposite sides thereof, as represented of one of the chains at 60. The other connection 58 is preferably a single length of'chain which is connected at its opposite ends to the rear upper end of the bucket and the front upper end thereof, as represented at 61 and 62 respectively, and veiitending intermediate its ends over a pulley 63 located betweenthe side plates of the carriage and journaled on 'a lcross-rod 64 thereon. The hauling means are the same as those described of the construction illustrated in Figs. l0 and ll.

The positions occupied by the parts of the apparatus just described, during the hauling of the carriage and the illed bucket up the cabley l5 are as represented in Fig. 12. As soon as thel carriage has been pulled up the cable far enough to cause its latch to interlock with the block 33, the operator slackens the cable 37 with the result of permitting the carriage 46 and bucket 56 to run for a slight distance down the cable 15, but as the latch 50 is in engagement with the block 33, said latch and the pulleys 53 connected therewith are held stationary relative to the movement of the carriage 46 in running down thc cable, and as the upper and lower ends of the chains 57 are connected with the carriage and bucket, respectively, and extend at their intermediate portions overv the pulleys 53, the movement of the carriage 46, as described, will, by pulling on the chains 57 swing the bucket 56 -to the dumping position illustrated in Fig. 13. The carriage 46 is provided across its top with a bar 65 projecting beyond the carriage opposite sides thereof and into the path of movement of which', as the carriage 46 from'an'd movable on said carriage to dumping and filling positions, a draft-cable connected with the scraper bucket and by which -Wlien pulled taut, the latter is held in loadcarrying position, locking means in advance of the limit of travel of said carriage and automatically engageable by said carriage,

and means operating automatically upon slackening saidAdraft-cabl'e to release said carriage`- from (saidI locking means.
